Undergrowth Stadium #359 from Commander Legends is a rare card that currently sells for about $6.71 ungraded, with graded copies ranging from $4.25 at grade 9 to $5.00 at grade 9.5. A grade 9.5 copy sells for around $5.00 vs $6.71 raw. That's a modest premium, so grading only pays off for near-perfect copies.
